The game focuses on “chat battles” that force players to trick their friends into saying certain words in Facebook chat. For example, Chat Fu will give you a target word like “lunch.” You then are tasked with getting your friend to say “lunch” without mentioning certain trap words like “sandwich.”

Your friend also doesn’t even need to know that you’re playing the game. To the other player, Chat Fu conversations show up as the typical private messages you’d expect to see with Facebook Chat. Chat Fu players can also share their victories by posting instant replays of their deceptive accomplishments on their Facebook walls.

Chat Fu is just a rather interesting Facebook game.

“It’s amazing how fun tricking your friends can be. Especially when they see it posted on their wall and try to get back at you! ”says Blot Interactive president and creative director Justin Kwok.

While silly, Chat Fu’s simple concept is very entertaining. If it catches on, it has the potential to become the next Words With Friends. Is anyone still playing that game by the way?
